The harp is a string instrument whose strings are plucked with the fingers. The modern concert harp has a large triangular frame, a resonating soundboard, and pedals that shorten the strings so the player can produce sharps and flats.

Its sound is luminous, cascading, and capable of both delicate arpeggios and powerful chords. Orchestral writing often uses the harp for coloristic effects, glissandos, and gentle accompaniment. Solo and chamber repertoire exploits its unique ability to play widely spaced chords and rapid scales.

Playing the harp requires coordination of both hands and both feet. The pedals must be set in advance for each key or chromatic passage. Historical harps without pedals or with different mechanisms appear in early music and folk traditions. The instrument’s visual beauty matches its sonic appeal.
